Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 9 To configure how the router handles ACFC in its outbound configuration requests, enter the following
command:
Router(config-if)# ppp acfc local {request | forbid}
Where:
• request—The ACFC option is included in outbound configuration requests.
• forbid—The ACFC option is not sent in outbound configuration requests, and requests from a
remote peer to add the ACFC option are not accepted.
For example, the following command creates how the router handles ACFC:
Router(config-if)# ppp acfc local request
Step 10 To configure how the router handles the ACFC option in configuration requests received from a remote
peer, enter the following command:
Router(config-if)# ppp acfc remote {apply | reject | ignore}
Where:
• apply—ACFC options are accepted and ACFC may be performed on frames sent to the remote peer.
• reject—ACFC options are explicitly ignored.
• ignore—ACFC options are accepted, but ACFC is not performed on frames sent to the remote peer.
For example, the following command allows ACFC options to be accepted:
Router(config-if)# ppp acfc remote apply
Step 11 Enable multilink PPP operation.
Router(config-if)# ppp multilink
Step 12 Enable real-time packet interleaving.
Router(config-if)# ppp multilink interleave
Step 13 Specify an identification number for the multilink interface.
Router(config-if)# ppp multilink group group-number
Where group-number is the multilink group number.
For example, the following command restricts (identifies) the multilink interface, 2, that can be
negotiated:
Router(config-if)# ppp multilink group 2
Step 14 Configure a fragment delay.
Router(config-if)# ppp multilink fragment delay
Where delay is optional and configures a maximum fragment delay. If, for example, you want a voice
stream to have a maximum bound on delay of 20 milliseconds (ms) and you specify 20 ms using this
command, MLPPP will choose a fragment size based on the configured value.
For example, the following command configures the delay from 0 to 1 millisecond:
Router(config-if)# ppp multilink delay 0 1
Step 15 Enable MCMP.
Router(config-if)# ppp multilink multiclass
